Free Tools App Store Description Generator

App Store Description Generator

Turn your app's features into App Store and Google Play copy — free, instant, no signup.

Writing store copy is where a lot of launches stall — not because founders don't know their app, but because App Store Connect and the Google Play Console want the same idea sliced into six differently-sized boxes, each with its own rules about what actually gets indexed.

This generator does that slicing for you. Enter your app name, what it does, and a short feature list, and it writes an iOS subtitle, promotional text, description and keywords field, plus a Google Play short and full description — each sized and structured for how that specific field is actually used by App Store Optimization (ASO).

Everything runs in your browser. Nothing is uploaded, nothing is stored, and the copy is a strong first draft, not a final submission — read it over and make it sound like you before it goes live.

Runs entirely in your browser. Nothing you type is uploaded or stored. Close the tab and it is gone.

Phrase it like "track your to-dos and get reminders that stick," not "it tracks your to-dos." Every field below is built from this.

Why the two stores read differently

  • iOS ranks off a separate 100-character Keywords field that shoppers never see, so its Description can stay written for a human reader.
  • Google Play has no keywords field — it indexes the description text itself, so the Android copy repeats your category and core benefit near the top on purpose.
  • Every field here is a strong first draft built from what you typed in. Read it before you submit — nothing here can verify a claim or catch a trademark issue.

Watch: how to use this tool

How to use it

  1. Enter your app name and a one-line description of what it does, phrased as an instruction (e.g. "track expenses and see where money goes").
  2. Pick a category and, if you want sharper wording, describe who it's for.
  3. List up to six real features — each one becomes a bullet in the description and a candidate keyword.
  4. Choose a tone and a call to action, then read the four App Store fields and two Google Play fields it writes.
  5. Copy whichever fields you need straight into App Store Connect or the Google Play Console, and press "Shuffle wording" if you want a different phrasing to start from.

Questions

Why does the iOS description look different from the Google Play one?
Because the two stores rank apps differently. Apple has a dedicated 100-character Keywords field that is never shown to users, so the App Store description itself can stay written for humans. Google Play has no keywords field at all — it indexes the description text directly, so the Android copy repeats the category and core benefit near the top on purpose, where Google's algorithm weighs it most heavily.
What's the difference between the Subtitle and the Promotional Text on iOS?
The Subtitle (30 characters) sits directly under your app name in search results and on your product page, and it only changes with a new app version. Promotional Text (170 characters) sits at the top of the description and can be edited any time — even between reviews — without submitting a new build, which makes it the right place for anything time-sensitive.
How should I fill in the Keywords field?
Apple's field is 100 characters, comma-separated, and the tool drops the spaces after each comma to fit more terms in — that's a real ASO trick, not a typo. It also leaves out any word already in your app name or category, because Apple already indexes those separately and repeating them just wastes characters that could hold a new term.
Can I just paste this straight into App Store Connect or Google Play?
You can, but you shouldn't without reading it first. This is a strong first draft built from what you typed in — it won't catch a factual error, a trademark issue, or a claim that doesn't hold up, because it has no way to know those things. Read every field before you submit, and adjust anything that doesn't sound like your app.
Is anything I type sent anywhere?
No. The whole thing is JavaScript running in your browser. Nothing is uploaded, nothing is saved, and closing the tab erases it.
What if I don't like the wording it picked?
Press "Shuffle wording." Each tone has more than one phrasing built in, so shuffling gives you a different opening and closing line without changing your inputs — a quick way to see two honest drafts instead of one.
